    • Thank you very much for your feedback and I have other question about stream quality.
      Why MS Edge always play first chunk of HLS stream with poor quality even if I have really good network speed? For example:
      http://live-api.miraclechannel.com/hls/miracle1.m3u8
      This playlist has three bitrates (256x192, 480x360 and 768x576). Player should detect network speed and start playback with detected bitrate but It looks like the player always load first chunk with poor quality and after that choose correct bitrate…
      Do you think that will be improved in near future?

    • Seems quite odd that Edge would claim HLS support despite only having implemented part of the spec. Would be nice if you’d more thoroughly document your support of the HLS and DASH specs and provide a roadmap. Native support is great (in theory), but if it’s spotty and not going to be maintained, then that can be more of a pain to deal with. Suppose that’s the plus of the MSE approach is that you’re not at the mercy of the browser vendors (assuming their MSE implementations are working correctly).
